A cleaner for Thai Airways International was killed Tuesday when she was struck and dragged under a trailer hauling freight containers at Suvarnabhumi airport.
Orapin Sunghom, a contactor with Kamphaeng Phet Cleaning Co, was hit by the pallet dolly while cleaning a plane and checking for suspicious objects in an aircraft parking bay.
She was found lying on the floor and later sent to Chularat 9 Hospital near the airport in Bang Phli district, Samut Prakan province, where she was pronounced dead.
The driver of the vehicle -- identified later by Suvarnabhumi airport police as Suphab Tiewtortrakul -- fled the accident scene, but was later arrested, Airports of Thailand Plc president Nitinai Sirismatthakarn and THAI president Charamporn Jotikasthira said.
Mr Nitinai said some pieces of the victim's clothes were found on the trailer.
"Police have taken over the case for investigation after the complaint was filed. Police will specify the cause of the death,'' he added.
An interrogation found that the driver, 45, was towing six containers to a plane and crashed into cleaner who was standing in a blind spot when he turned, according to Pol Lt Col Kunchawis Phoprasit, a duty officer at Suvarnabhumi airport police station.
Mr Suphab was charged with reckless driving causing death.
The accident took place as Suvarnabhumi celebrates its ninth anniversary. It opened for service on Sept 28, 2006.
